Dear Gordon

I isolated a fortuitous tandem copy of a GFP fusion to the N-terminus
yeast calmodulin.  In this case even over-expression of the double GFP
fusion failed to complement when an integrated fusion containing single
copy GFP did.  The signal I got from one copy of S65T was more than
sufficient to visualize the fusion by eye through the microscope. Just my

Happy GFPing,
